Plok is a wonderful Super Nintendo game, and its title hero has been the profile image for my music stuff forever now. He's sort of my music's de facto mascot. There's no special reason behind it. I just used a random PNG of Plok when I made my YouTube channel way back, and every now and then people would recognize him and say nice things, so I always make sure my profile pictures feature him. I even have a Photoshop file with all his limbs on different layers so I can easily make new ones. The creator of Plok actually commented on it once. It was just a small thing, but it really made my day. It meant a lot to me. I guess if you do something long enough, people will eventually notice.
